Code & Encoding Tools
Handy, safe utilities for developers and power users. These tools run fully in your browser, so code, keys and text you paste never leave your machine.
Typical uses
- Encode or decode Base64 for data URLs, JSON and authentication payloads.

Saving you trips
Small, reliable helpers remove the need to open a terminal or an external service for everyday tasks. Because processing is local, there is no risk of a third party seeing the text or tokens you work with.
